I have no glow plug activation, unless I unplug the engine coolant temp sensor. Ohm readings on sensor appear normal[394 ohms at 190 degrees]. 4 pin harness connector terminal 1 to 3 = .89 ohms[OK?,less than 1.5]. but I have no resistance between any combination of terminals 1-2-4 of that 4 pin harness connector.
